This European Standard supports industrial
20、 activities in the area of biotechnology covering operations with including non-genetically modified micro-organisms and genetically modified micro-organisms (GMMs) and with both non-pathogenic and pathogenic micro-organisms (see annex B 1, 2). NOTE. Non-genetically modified micro-organisms include
21、natural micro-organisms and micro-organisms improved by traditional techniques. The plant buildings used for biotechnological processes vary widely. The characteristics of each plant building will be dictated by the physical containment to be used at each stage of operation based on risk assessment.
22、 This assessment can indicate that some requirements in a given situation are not necessary or that a higher level is needed. For animal and plant pathogen micro-organisms, a case by case analysis should be done. 1 Scope This European Standard specifies design requirements for plant buildings used f
23、or the safe handling of micro-organisms and the product itself if it presents a biohazard. NOTE 1. When applying this European Standard, attention is drawn to the existing national regulations such as regulations concerning genetic engineering, water and environmental emission concerning the design
24、requirements. Plant buildings include buildings intended, if necessary, to contain all the fermentors and downstream processing apparatus. Plant building design includes design of equipment linked to the building itself and excludes specific production equipment. NOTE 2. Equipment implementation is
25、covered by a standard Equipment implementation according to the degree of hazard which is being prepared (see annex B 3). This European Standard is not applicable to design requirements which affect good manufacturing practice (see annex B 6) or product quality, for which attention is drawn to relev
26、ant codes of practice and national regulations. It would be advisable to consider both aspects simultaneously. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places
27、in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.

29、andard, the following definitions apply: 3.1 biohazard Intrinsic potential property or ability of micro-organisms/organisms, and/or biologically active substances to cause harm. 3.2 closed phase Period during which the micro-organisms/organisms are separated by a barrier from the environment. 3.3 cl
30、osed system System where a barrier separates micro-organisms/ organisms from the environment. 3.4 controlled area Area constructed and/or operated in such a manner as to limit contamination of the other areas by micro-organisms/organisms from within the controlled area. 3.5 hazard Intrinsic potentia
31、l property or ability of something (e.g. any agent, equipment, material or process) to cause harm. NOTE. Harm is an injury or damage to health of people and/or to the environment. 3.6 inactivation Destruction of micro-organisms. 3.7 micro-organism Any microbiological entity, cellular or non cellular
32、, capable of replication or of transferring genetic material (EN 1619). NOTE. The term micro-organism covers the term of biological agent, according to the Directive 90/679/EEC: micro-organisms, including those which have been genetically modified, cell cultures and human endoparasites, which may be
33、 able to provoke any infection, allergy or toxicity. 3.8 open phase Period during which the micro-organism/organism is not separated by a barrier from the environment. 3.9 open system System where there is no barrier between the micro-organism/organism and the environment.Page 4 EN 1620 : 1996 BSI 1
34、997 3.10 physical containment System for confining a micro-organism/organism or other entity within a defined space. 3.11 primary physical containment System of physical containment which limits the escape of a micro-organism/organism into the working environment. NOTE. This can involve the use of c
35、losed containers or appropriate equipment together with secure operating procedures. 3.12 risk Probability of occurrence of a hazard causing harm and the degree of severity of the harm. 3.13 secondary physical containment System of physical containment which limits the escape of a micro-organism/org
36、anism into the environment or into other working areas. NOTE. This can involve the use of rooms with specially designed air handling, the existence of airlocks and/or sterilizers for the removal of materials and secure operating procedures. In many cases it can add to the effectiveness of primary ph
37、ysical containment. 4 General considerations As a preliminary, a risk assessment shall be carried out on the process to determine the likely containment levels. The following safety aspects shall be taken into consideration, where appropriate, when handling micro-organisms: protection of personnel;
38、protection of the environment; protection of the product. Buildings shall be designed to prevent the potential risks by taking into account: a) the degree of biohazard; NOTE. Annex A gives a common basis for classification. b) the route of exposure to the biohazard; c) the mode of handling: open or
39、closed system, open or closed phase. The result shall be the establishment of controlled areas giving the required levels of containment. 5 Design requirements 5.1 Plant building in general Table 1 gives a combination of measures which may be combined to give necessary levels of containment. However
40、, it is emphasized that it may be appropriate to select and combine requirements from different containment levels on the basis of risk assessment related to any particular process or part of a process. Particularly, plant design which is intended for secondary physical containment, shall be adapted
41、 to the level and reliability of primary physical containment. It is also necessary to comply with national and European regulations. For micro-organisms pathogenic only to plants or animals, but not to humans, requirements for building design shall be adapted, case by case according to the type and
42、 the degree of hazard of this micro-organism. These considerations shall include the epidemiological situations of the plant or animal pathogens (e.g. endemic area). Plant buildings should be designed to permit effective application of the principles of good occupational safety and hygiene (GOSH) (s
43、ee annex B 4) and good industrial large scale practice (GILSP) (see annex B 5). Plant buildings shall be easy to clean and maintain. Plant buildings shall be designed in order to permit control of gas, liquid and solid releases, where appropriate, in accordance with national and European regulations
44、. NOTE. A standard Guidance for the handling, inactivating and testing of waste is being prepared (see annex B 8). The main points to be considered are listed as follows: a) barriers between outside and inside controlled areas such as walls, floors, ceilings, doors, windows; b) retention system to r
45、etain spillage/leakage of the content of a closed system; c) inlet/outlet from a controlled area for: liquids; solids; gas; personnel (see prEN 12307); equipment; communication; energy. 5.2 Plant building design for containment level 1 There are no special design requirements except general requirem
46、ents. Special requirements only intended to protect the product if necessary, are outside the scope of this standard but they should be considered together with general design requirements. Building design containment level 1 corresponds to a basic building used for fermentation. NOTE 1. Some fermen
47、tations and/or some contained downstream processes, are carried out outside a building; these correspond to a closed system outside of a controlled area. In this case, this standard can not be applicable. Some fermentations are carried out in an open system in a controlled area (for instance cheese
48、fermentation). In this case this standard can be applicable. NOTE 2. A standard Procedures for fermentation and downstream processes is being prepared (see prEN 12075).Page 5 EN 1620 : 1996 BSI 1997 5.3 Plant building design for containment level 2 A containment level 2 plant building shall be desig
49、ned so as to minimize the escape of micro-organisms (see table 1). The following requirements shall be observed in addition those specified in 5.1 and 5.2: a) the controlled area shall be clearly identified; b) bench surfaces shall be easy to clean and disinfect; c) doors and windows shall be closeable; d) where appropriate, the controlled area shall be adequately ventilated to minimize air contamination; e) a biomass inactivation system shall be available; f) where appropriate, the controlle
